What is the Box Shadow Generator?
The Box Shadow Generator is a free visual tool for designing CSS box shadows with precision and ease. Shadows are essential in modern UI design for creating depth, hierarchy, and visual separation between elements. This tool lets you build complex multi-layer shadows by adjusting horizontal and vertical offsets, blur radius, spread radius, color, and opacity for each layer independently. You can see your shadow applied to a live preview element in real time and instantly copy the production-ready CSS code. Whether you need a subtle card elevation, a bold button hover effect, or a layered neumorphic design, this generator gives you the visual control to get the shadow exactly right.
How to Use the Box Shadow Generator
- Start by adjusting the horizontal and vertical offset sliders to position your shadow.
- Set the blur radius to control the softness and the spread radius to expand or contract the shadow.
- Pick a shadow color and adjust the opacity for subtle or dramatic effects.
- Add additional shadow layers to build complex, realistic depth with the add layer button.
- Copy the generated CSS box-shadow property and paste it into your stylesheet.
Use Cases
- Card components in dashboards and content feeds that need subtle elevation
- Button hover states with smooth shadow transitions for interactive feedback
- Modal dialogs and dropdown menus that need to appear above page content
- Neumorphic UI designs with soft inset and outset shadow combinations
- Navigation bars and sticky headers with bottom shadow for depth separation
Frequently Asked Questions
How many shadow layers can I add?
You can add multiple shadow layers to create complex, realistic depth effects. Each layer has independent controls for horizontal and vertical offset, blur radius, spread radius, color, and opacity. Layering shadows is how professional designers achieve soft, natural-looking elevation effects.
What is the difference between box-shadow and drop-shadow?
CSS box-shadow applies a shadow to the rectangular box of an element, while the drop-shadow filter follows the actual shape of the content including transparent areas. Box-shadow is more commonly used for cards and UI elements, supports multiple layers, and offers the inset option. This tool generates box-shadow CSS.
What are the best practices for using box shadows in UI design?
Use subtle, layered shadows with low opacity to create natural depth. Avoid hard, dark shadows that look dated. Match your shadow direction consistently across the interface. Use larger blur values and slight vertical offsets to simulate overhead lighting. Reserve stronger shadows for elements that need to appear elevated, like modals and dropdowns.
